Kexec on Nokia N900

[pali]

I installed power kernel, downloaded and unpacked bootimg of new kernel. Next I called:

kexec -l <img> --command-line="`cat /proc/cmdline`"
sync
kexec -e

In framebuffer console it show something like booting new kernel bye... and N900 freeze. After some seconds rebooted and it does not load new kernel.

Where is problem? How to kexec other kernel on Nokia N900?

[pali]

Any ideas?

I think that the watchdogs are rebooting the device when you kexec. have you tried disabling them?

[pali]

yes, watchdogs reboots device. This is normal when kernel freeze!

But my question is why kexec does not work? (or how can I correctly use kexec?)

[pali]

Does anybody successfull load another kernel using kexec?
